Answer:
Normal, Gravity, Friction, and Air Resistance.
Explanation:
When a moving car skid to stop and its wheels are locked across, then the following forces will be applied on the car:
<u>Normal force:</u> It will act counter to gravity that pushes an object against a surface and acts perpendicular to the contact surface.
<u>Gravity:</u> Gravity force acts in each and every object having mass and it can not be avoidable. So, the gravity force will also apply to the car and attract it to the earth's surface.
<u>Friction: </u>Friction is a force that acts opposite to the motion and stops or slows motion. Friction will be applied to the car that will oppose the motion of the car and stop it.
<u>Air resistance:</u> air resistance is defined as the forces exerted by air that acts opposite to the relative motion of an object. Air resistance will also be applied to the car when it will skid to stop as we are always surrounded by the air.
Hence, the correct answers are "Normal, Gravity, Friction, and Air Resistance."
Answer:
4
Explanation:
As you can see in the free body diagram there are 4 forces acting on the body.
Answer:
melting of rock deep underground.
Explanation:
The melting of rocks deep underground does not produce sedimentary rocks. Most igneous rocks are produced by this process.
When molten rocks underground called magma is solidified in the subsurface, it results into the formation of igneous bodies.
- Sedimentary rocks forms by the accumulation of sediments.
- Inside the basin where the sediments are deposited, they are compacted, cemented and lithified.
- Chemical and physical weathering of rocks produces sediments.

Weightlessness is the condition where the body has zero gravity ( its acceleration is equal to the acceleration due to gravity )
